Michel Dänzer b97c7c78c5 xwayland: Always hook up frame_callback_list in xwl_present_queue_vblank 
Even if there's no pending frame callback yet.

Without this, if there was no pending frame callback yet in
xwl_present_queue_vblank, xwl_present_msc_bump would only get called
from xwl_present_timer_callback, resulting in the MSC ticking at ~58
Hertz.

Doing this requires some adjustments elsewhere:

1. xwl_present_reset_timer needs to check for a pending frame callback
   as well.
2. xwl_window_create_frame_callback needs to call
   xwl_present_reset_timer for all child windows hooked up to
   frame_callback_list, to make sure the timer length takes the pending
   frame callback into account.
3. xwl_present_flip needs to hook up the window to frame_callback_list
   before calling xwl_window_create_frame_callback, for 2. to work.

Closes: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1309
Fixes: 9b31358c52 ("xwayland: Use frame callbacks for Present vblank events")

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
